[Unusual forms of laryngeal carcinoma]

From 1976 to 1983 we monitored 439 patients who were treated at the Radiotherapy Unit of University Clinic of Cádiz. Of all the patients who were examined we discovered only six cases of unusual histopathological forms of carcinoma of the larynx, representing 1.36%. The survival in the case of these patients was studied five years later. From the study we conclude that survival in the case of these patients is not affected by histopathological type of tumor, but, as in the case of epidermoid tumors, influencing factors are: anatomical situation, extension and type of treatment followed. The index of survival is similar to that observed in epidermoid neoplasm of the larynx.
